Which statement below best describes the curvature effect?
A) Large cloud droplets fall faster than small droplets.
B) Small droplets evaporate more quickly than large droplets.
C) Small droplets collide and coalesce more easily than larger droplets.
D) It explains the six-sided shape of ice crystals.

Question

Quizplus · Accepted Answer

The curvature effect states that small droplets have a greater curvature at their surface than large droplets, which leads to a stronger surface tension. This stronger surface tension results in faster evaporation of small droplets compared to large droplets.

Answer: C 
 The curvature effect also explains why small droplets are more likely to coalesce or collide with each other. The stronger surface tension caused by the greater curvature of small droplets causes them to attract and merge more easily than larger droplets.

Answers A and D are not related to the curvature effect but rather to other phenomena in atmospheric science.
